What does the auto switch mean?

[SanCayden]

auto switch in cars is commonly found in air conditioning systems, windows, and auto start-stop systems: 1. auto on air conditioning: pressing the switch allows the air conditioning system to automatically adjust its temperature and fan speed according to environmental changes; 2. auto on windows: once activated, pressing the window button once will automatically close or open the window without the need to hold the button; 3. auto in start-stop systems: enabling this function allows the car to automatically shut off the engine during brief stops to reduce fuel consumption. Engine auto start-stop automatically turns off the engine when the vehicle comes to a temporary stop during driving.
